What happens is that you can see that the density of a nail is more than the density of water and that the density of a cork is less than that of water.
The nail sinks in water because the gravitational force attracts it downward toward the earth, there is an upthrust of water on the nail which pushes it upwards but, the downward force acting on the nail is greater that the upward force. Hence, the nail sinks in water. The density of the iron nail is more than that of the water, this means that the upthrust of water on the iron nail is less than the weight of the nail, so it sinks. The cork floats while nail sinks this happens because of the difference in their densities. The density of a substance is defined as the mass per unit volume. The density of the cork is less than the density of water. This mean the upthrust of the cork is greater than the weight of the cork. The density of the iron nail is more than that of the water, this means that the upthrust of water on the iron nail is less than the weight of the nail, so it sinks.
The cork piece floats because it is less dense than water, allowing it to displace enough water to support its weight. The iron nail sinks because it is denser than water and does not displace enough water to counteract its weight, causing it to sink.
Correct me if I'm wrong, but i believe that cork floats on water because its cells are empty.Any object dropped into a liquid displaces that liquid. A floating object weighs the same as the liquid it displaces. An object that sinks, weighs more than the liquid it displaces, so the stone is heavier than the cork causing it to sink. and not just that, cork is a lot less dense than a stone is.
yes it does. try to sink a cork. it doesn't sink but on the other hand a iron nail does.the higher the mass the more the density and so the object sinks.
Iron has a higher density than water, so it sinks in water; but is less dense than mercury so it floats.
The iron nail sinks in water because its density is greater than that of water. The katori floats because its shape and material make it less dense than water, allowing it to displace enough water to generate a buoyant force greater than its weight.
A boat floats because the weight of the water it displaces is equal to the weight of the boat, creating buoyant force. A nail sinks because its density is greater than that of water, causing it to be heavier than the water it displaces.
An object will sink if its density is greater than that of water (or another liquid in which it is placed). If its density is less, it will float. In the case of the ship, the air in the ship helps reduce the total density.
Wooden cork is less dense than the water and the iron is not.
Because iron is rusting.
The steel ship has a lot of air inside. The nail is solid steel.
Have you heard of Archimedes. Well he stated that the weight of water displaced by an object is equal to the weight of the object. From here we conclude that object being more denser than water sinks those being less dense than water floats. An Aluminum cube has a much higher density than that of water and the sheet is less dense than water. Thus the former floats while the latter sinks. Now you also might have noticed that an iron nail sinks while an iron ship floats. I hope now you can answer this question!!
